Tassili N’Ajjer National Park in Southeastern Algeria25.5N 9.0E
The Tassili N’Ajjer National Park, in the Tassili N’Ajjer Mountains, is a World Heritage Site in Algeria. It is located on a plateau of outstanding scenic and geological interest (dark brown areas), covered by eroded sandstone forests of rock.
The area is a floristic and faunal island of Sahelian life in the middle of the desert, and harbors a relict Mediterranean cypress, one of the rarest trees in the world. It also has one of the largest and best preserved groupings of prehistoric cave art in the world, an immense gallery of neolithic art of international importance.
The park has a surface area of 8,000,000ha (Biosphere Reserve 7,200,000ha). It is located in the central Sahara in far southeastern Algeria. The northern boundary runs east 440 kilometers (km) from Amguid on the Tamanrasset road via Illizi to the Libyan border. The east and south sides adjoin the Libyan and Nigerien borders for 600km. The southern boundary runs northwest 700km from the Nigerien border to Amguid, bulging in to exclude the sands of Erg d’Admer.
